In a new animal-themed cafe, 20 to 30 hedgehogs of different breeds scrabble and snooze in glass tanks in Tokyo's Roppongi entertainment district. A fee of 1,000 yen ($9) on weekdays and 1,300 yen on holidays brings an hour of playing with and cuddling – carefully – the prickly mammals, which have long been sold in Japan as pets despite not being native to the island nation. Staffer Mizuki Murata, who also works in a rabbit cafe in the same building, said the shop had been popular since its February opening, with customers often having to queue. The cafe's name Harry alludes to the Japanese word for hedgehog, harinezumi. (Photo by Thomas Peter/Reuters)
